Indeed.
I regret that SubD/QFT quads don't export as quads correctly, otherwise Blender has very good unwrap tools. But as it is now, Sketchuppers are forced to work with SketchUV or WrapR for their UV tweaking.
And unfortunately WrapR is damn slow/not featured enough compared to Max or Blender counterparts.
The workable polycount is very low. It's only usable for small models with low complexity. The Undo is not always working/too slow. In Substance Designer, I often tend to rely more on the beta Unwrapper on an straight (no-unwrapped) fbx exported from SU because of that...

I think this plugin is underrated because it's too expensive for its features (and because the casual Sketchupper don't care abut Unwrapping) and therefore too small userbase to really push it forward.

I dream that Thomthom takes the code and embeds it in his QuadFaceTools v2, working hands in hands with VertexTools 2 and SubD 2... For me, it would make sense as WrapR can't work without quads anyway, and so is dependent on QFT and SubD...

I never understood how relax worked in WrapR... It's way too slow too.
Is WrapR still under development? There are so many things I'd like to ask...

Bonjour,
Qu'en est-il aujourd'hui?
Toujours pas d'exporteur STEP depuis SketchUp?
Dois-je obligatoirement passer par 3dsMax?

Sacré Pilou!!! Toujours fidèle au poste

Ah thanks. I'll try to install it independently.

almost for sure you have faulty linework

Did you try? trace 2 separate lines and try to extrude them?

Hello all,

I just installed the JHS powerbar in SU 2020 Pro and so far, I got one bug (but an annoying one):
When I use EXTRUDE LINE (by Didier Bur), SU hangs when trying to extrude more than one line at once.
Previously, I had no problem doing that (2015 2016 2017 2018 2019).
Now I must be aware that SU crashes (or hangs for eternity) when doing that.

Indeed. But Thomthom could update his Raytracer too; just add an option to drop the vertices on a target mesh (he already has the command to drop Cpoints - btw I love the Drop with Trace option)

Thanks Marcello for the long didactic video ! Very clever, you're a genius!
This method should work in most simple cases indeed. Flowify rules! The thing is, not to forget to use Flowify WITHOUT CUT, and to keep things simple.
In the past, I used Instant Road but it produces messy meshes, impossible to edit anymore and you need to keep track of each iteration of the terrain, just in case you need to change road position, height, crossings, etc.

Ah sorry for the misunderstanding. I agree that Flowify is robust.
I'm meaning, I'd work with small patches at a time because SubD becomes unstable and slow to edit with huge meshes, not to mention the errors and the time it needs to pinpoint the culprit vertices.

PS I'm not used to see fast replies on this thread

By the way, I was looking for some workaround with

1. C-points at vertex (TiG) of the quad mesh
2. Drop C-points on the target mesh with Raytracer (Thomthom)
3. trying triangulate points (TIG) but ended in a mess, so I was looking for a script to recreate a quad mesh from the dropped Cpoints...

Impressive modeling video!
Not exactly what I'm looking for but impressive nonetheless!

Let's say I have a simplified 3d mesh from a topographic survey (drawn from isohypse lines and meshed with toposhaper for instance). Very complex and heavy, and full tris so impossible to edit quickly.

Then I have a site in quad topology modeled in 2D from CAD plans with correct projections of roads, buildings rivers, and so on.

Right now, I move manually each vertice of my quad site to fit the correct height of the topographic mesh, beginning by the roads, then outlines of buildings, etc.
Of course, I use separated groups to keep the quads from merging with the tris, and I regularly test if SubD works without generating errors) and save a lot.

For complex sites, it takes hours. I enjoy the zen attitude when modeling sites but sometimes I realize that it's very repetitive and boring.

So, what I'd like is a script that 'drapes' the vertices of my quad mesh on the topographic mesh with one click, just like the sandbox's drape tool but that keeps the quads, so I can keep subDing afterwards, and of course further editing because the project always evolves...

Thomas, is there a "drape" a quad mesh on a "target" triangulated mesh (in another group, serving as a reference) along Z axis?
I'm fond of your "Flatten selection" command in Architect Tools, but I'm looking for a tool that basically "drops" all the vertices of a quad group on a target triangulated mesh group, while keeping the first group as quads.

Hi Thom!

One thing that annoys me is the fact that I need to quit Vertextools mode to select quad loops or rings with QFT... Is it not possible to get loop/ring selections while in Vertex tool ?

Just wondering...

I would appreciate your help since when I install the quadface tools plugin the plugin toolbar does not appear. I have installed it in sketchup 2018 and 2019

Right-click an icon on the toolbar zone and check if the QuadFace Tools is checked on.

Vertex tools is really a must have in my toolset, it's so handy to have when dealing with complex geometry...

Is V2 allowing easier placement of gizmo for scaling/rotating/moving? By default, the scale/rotate uses a gizmo position centered on the selection. But sometimes I'd like to manually move the gizmo to define another center for the scaling/rotating, like on a vertex or the edge of the selection.

A quick and dirty way, like Ctrl + move along the axis would move the gizmo without altering the geometry... or something like that.

And what about a 'smart' offset of a loop/ring? Kind of SU offset tool but that works in 3d space too.
Imagine a curved road (in XY but also in Z too) and you'd need to quickly offset the rim edges to add the shoulder, curbing, drainage, walkway, etc.
In 2d space it's easy as SU offset tool works but if the site is not flat it's another story...

I suppose it's similar to the extrude with scaling demand I saw earlier in the thread...?

If the selection is planar I usually create a face and use FREDO JointPushpull's Follow pushpull which takes into account the connected faces, but it would be handy to be able to do that with a non coplanar edge selection.

Ok, thanks a lot! Indeed it works!

Btw I don't care about the triangles I left. Anyway the topology isn't perfect to begin with, because the source mesh (although very correct for a 3DWH skp) isn't mine and the first purpose wasn't subdivision but getting some UV for Skattering or WRapr.

Got the problem on a whale model I downloaded from the WH and quadifying it.

test file

I have a strange behaviour too...
The flowify command generates a huge model, with an array of sectional faces.

First the source material: Group 1 composed of A target surface / B source surface / C projection vectors and D the source mesh (exploded)

The resulting groups from the flowify command

I succeeded all the other meshes with the same method but here I've got a bug...

The skp

Btw, do you have some quad that are not fully QuadFace quads? I see some unexpected uneven edges in the back there:

[attachment=0:1mfg7n1x]<!-- ia0 -->2019-01-19_13h26_35.png<!-- ia0 -->[/attachment:1mfg7n1x]

This is the same strange behaviour I got last year with some meshes. Dunno why, but it seems that some vertices react as a 1.0 crease when subdivided although they are 0 when checked with the crease tool.
I usually delete the problematic edges and redraw the geometry from scratch when that happens.
